It often means they do not get into the spaces they will be performing in until just before the shows.
"This is just half time for us because the PSG players are coming to Paris," he said, with a celebration expected around the Parc des Princes where players will meet fans."There again we are expecting some clashes, some scuffles and we will be there and we will be very strong in our response against the vandals, against the thieves who have a go at the police officers.
"We will not tolerate any abuse today and the fans who want to enjoy the parade, can do so safely."He added that "PSG supporters shouldn't be mixed up with gangs of looters and vandals".Separately, the Paris Prosecutor's Office told the BBC "several shops were looted" in the Place des Ternes area. About 30 people were arrested and taken into custody near a Foot Locker on the Champs-Elysées that was robbed, the office said.
Elsewhere across France, Dax mayor Julien Dubois, reacting to the fatal stabbing, said his "thoughts are with the young victim, his family and friends"."We are floored by all the drama tonight," he wrote on social media. "It is advisable to quickly shed light on these facts in order to severely punish the perpetrator."

The Eiffel Tower was illuminated with PSG's blue and red colours.When Byunghui arrived at the protests, she was struck by the atmosphere.
The bitter December cold didn't stop tens of thousands of women from gathering. Huddling inside hooded jackets or under umbrellas, waving lightsticks and banners, singing hopeful K-pop numbers, they demanded Yoon's ouster."Most of those around me were young women, we were singing 'Into the World' by Girls' Generation," Byunghui says.
Into the World, a hit from 2007 by one of K-pop's biggest acts, became an anthem of sorts in the anti-Yoon rallies. Women had marched to the same song nearly a decade ago in anti-corruption protests that ended another president's career."The lyrics - about not giving up on this world and dreaming of a new world," Byunghui says, "just overwhelmed me. I felt so close to everyone".
